Abstract

Chemical group 1 (CG 1) consists of straight-chain primary aliphatic alcohols/aldehydes/acids, acetals and esters with esters containing saturated alcohols and acetals containing saturated aldehydes of which 86 are currently authorised for use as flavours in food. The FEEDAP Panel was unable to perform an assessment of ethyl oleate because of its insufficient purity. The following compounds are considered to be safe for all animal species at the use level proposed for feed flavourings: formic acid, acetic acid, propionic acid, octanoic acid, decanoic acid, dodecanoic acid, tetradecanoic acid, hexadecanoic acid, oleic acid, decanol, dodecanol, decyl acetate and dodecyl acetate. The remaining substances are considered safe for all animal species at 5 mg/kg complete feed (with a margin of safety between 1 and 120) and at 25 mg/kg complete feed (ethyl acetate and hexyl acetate, with a margin of safety between 2 and 6); and at 1 mg/kg complete feed for pigs and poultry and 1.5 mg/kg complete feed for all other species (ethylacrylate, ethyl hex-3-enoate, ethyl trans-2-butenoate, ethyl isobutyrate, ethyl isovalerate, butyl isovalerate, methyl isovalerate, hexyl isobutyrate, methyl 2-methyl butyrate, pentyl isovalerate, butyl 2-methyl butyrate, hexyl isovalerate, ethyl 2-methyl butyrate, hexyl 2-methyl butyrate and methyl 2-methylvalerate). No safety concern would arise for the consumer from the use of compounds belonging to CG 1 up to the highest safe level in feedingstuffs for all animal species. The FEEDAP Panel considers it prudent to treat all compounds under assessment as irritants to skin, eyes and respiratory tract and as skin sensitizers. No risk for the safety for the environment is foreseen. Since all 85 compounds are used in food as flavourings, no further demonstration of efficacy is necessary.
